' CHAPLET FOR MOLDING.

Application filed April 4, 1925. Serial No. 20,727.

The present invention is an improved chaplet for use in molding to prevent displacement of the core in molds or molding flasks.

The object of the invention is the pro-- duction of a more durable chaplet using less metal in its construction while at the same time giving more support and strength thereto, due to its particular construction, as a consequence rendering the chaplet more compact, more evenly balanced, and utilizing all material of the blank from which it is made.

Broadly, the invention resides in a chaplet of maximum compression strength for the amount of metal used in its construction. The struts are obtained by cutting the blanks one from the center, and the other from the outer edge of the blank which carries a suitable extension for this purpose. The struts are bent to extend at right angles and, because of the manner in which they are obtained, are of a width or length to support a maximum surface of the top and bottom plates. The free ends of the struts may be bent at any desired angle to give added strength and rigidity thereto, the opening formed by bending the strut obtained from the center of the blank enabling the metal to flow therethrough without obstruction.

The invention further resides in the sundry details of construction, combination and arrangement of parts shown and described, and pointed out in the appended claims.

In this specification and the annexed drawings, the invention is disclosed in the form in which it is considered to be the best, but the invention is not limited to such form because it is capable of being embodied in other forms; and it is to be understood that in and by the claims following the description herein it is intended to cover the invention in whatever form it may embody within the scope thereof. 1

In the drawings which show the preferred embodiment of the invention as at present devised Figure 1 is a plan view of a blank from which the chaplet is made, its flexibility being indicated in dotted lines.

Fig. 2 is a front elevation of the chaplet constructed from the blank shown in Fig. 1.

Fig. 1 is a plan view of a blank for a slightly modified form of chaplet.

Fig. 5 is a front elevation of the chaplet constructed from the blank shown in Fig. 1.

Fig. 6 is a horizontal sectional View taken substantially on line 66 of Fig. 5.

Fig. 7 is a plan view of a blank similar to that shown in Fig. 1, but produces a chaplet which is a multiple of that shown in Fig. 2. Fig. 8 is a side elevation of a completed chaplet made in the form shown in Fig. 7 its flexibility being indicated in dotted lines. Fig. 9 is a cross-section of the chaplet shown in Fig. 8, taken substantially on lines 9-9 of Fig. 8. V

Fig. 10 is a horizontal sectional view taken substantially on lines 10-10 of Fig. 8.

Referring particularly to the drawings, in which like characters denote similar and like parts referred to in the specification, and referring particularly to Fig. 1, 1 indicates an elongated blank of desirable width and length to provide the chaplet shown in Fig. 2, which is substantially square. The blank has formed thereon a lateral extension a: at a medial portion of one edge, as shown. The blank 1 may be stamped from a strip of sheet stock and during the operation may be out to produce the various slits or cuts for forming wing flanges or struts 2. The blank is cut transversely along the medial portion thereof to provide parallel slits ab and ccZ, the slits ac and bal being spaced and in alignment. The slits cd extend across the greater portion of the width of the blank between its side edges and are connected at their ends nearest the extension 00, by a slit or cut 2'. The end or marginal portions 8 and 4 of the blank are folded toward each other on the dotted lines j, which are coincident with said parallel cuts and thus provide the top and bottom plates, respectively, of the chaplets, as clearly seen in Figs. 2 and 3. The parts 5 lying between the parallel cuts above described form connecting uprights, integral with one edge of the top and bottom plates 3 and 4E. Fromthe drawings it will be ob served that the extension w forms part of one strut, while the other strut is obtained entirely from the center of the blank, the struts 2 being integral with one edge of each upright 5, and each adjacent strut being connected to the corresponding edge of the adjacent uprights.

This manner of cutting the blanks produces chaplets having their supporting elements distributed to support the top and bottom plates at points most needed and produces wider struts which will extend a greater distance between the plates 3 and 4-, whereby greater compression strength is obtained in a more compact form. The struts 2 are bent on the dotted lines 7: at right angles to the uprights 5, and lie between the top and bottom plates. It will be clear that the present invention provides the struts 2 of a width which will extend across the top and bottom plates for a distance at least one-half the width of said plates, for the purpose of giving to the outer free edges of the plates 3 and 4. the requisite support needed, while having definite uprights 5 at the back of the chaplet connecting the top and bottom. The outer or free ends of the struts 2 are bent on a line Z at an angle (which may be any desired angle) to the body of the struts to provide additional supports 7 between the top and bottom plates 3 and 4:. Any suitable portion of the chap let may be perforated to allow metal to flow therethr-ough.

Manifestly, by virtue of this construction, a chaplet of any desired length can be made from a single strip of material with substantially no loss of material and with its supports equally distributed to give the greatest possible strength to the top and bottom plate; and when required, the construction may be in multiple, as shown in Figs. 7 to 10, without destroying the equal balance or distributed support of the chaplets.

The form of ohaplet shown in Figs. '7 to 10 may be constructed from a wider blank 6, as shown in Fig. 7, which is the same as the blank in Fig. 1 except for having an additional duplicate section. This duplication may be extended in any multiple for cer tain work where long Chaplets are desired. The like and corresponding parts or the blank and chaplets shown in Figs. Y to 10 bear the same reference characters as in the preceding figures, except being raised by the exponent prime.

As indicated in Figs. 2 and 8, the chaplet is capable of being flexed to meet the desirec requirements, due to the equal distribution of the supporting members 2 and 5.

In Fig. 4- another form of blank is shown, from which the chaplet shown in Figs. 5 and 6 is formed. The blank 8 is out or otherwise formed to produce at its end side the outwardly projecting portions 9, which are located at a medial point of said side edges and ultimately form the wing flanges which lie between the top and bottom plates 10 and 11. The width of the portions or flanges 9 is such as is desired for the size of chaplet being made, and the blank is cut inwardly on the line m, n, 0 and p, from said end edges and on opposite sides of the wings 9, as clearly shown in d. The portions 10 and 11, which form the top and bottom plates, are bent towards each other and on lines coincident with the cut m and 0, and n and p, to right angular position with respect to the center portion 12, which forms a relatively wide upright; but, in order to permit a tree flow or the molten metal about the chaplet, this upright 12 may be perforated. The wing flanges 9 are bent on lines Q and r to lie at right angles between the top and bottom plates 10 and 11, and extend transversely across the latter "for a distance at least, but preferably greater, than one-half the width of said plates. The outer or free ends of the wing flanges 9 are bent on lines 8 and t, respectively, to extend at any desired angle to the body or said flanges 9, for the purpose of giving additional support to the plates 10 and 11, in the direction of their length, as shown in Figs. 5 and 6.

From the foregoing it will be observed that chaplets of greater durability and strength are provided, using a minimum of stock and being compact in construction and well l alanced.
